EV Installations

The negative of the Link 10's power supply must be common to the negative of the battery (motive pack) which you are measuring. This may pose difficulty if your electric vehicle uses an "unbonded" or "floating" (no connection to the chassis) motive pack and a "bonded" (connected to the chassis) accessory battery. In these instances, the use of a DC-DC con- verter, or a separate battery with a common negative with the motive battery is required. This device provides power for the Link 10 without electrically connecting the motive battery negative to the chassis. The diagram shown is for a typical DC-DC converter. If you use a different DC-DC converter, the pin-out may be different:
